We can normalize a histogram in Matplotlib using the density keyword argument and setting it to True. By normalizing a histogram, the sum of the bar area equals 1.
Consider the below histogram where we normalize the data:
nums1 = [1,1,2,3,3,3,3,3,4,5,6,6,6,7,8,8,9,10,12,12,12,12,14,18]nums2= [10,12,13,13,14,14,15,15,15,16,17,18,20,22,23]
fig,ax = plt.subplots() # Instantiate figure and axes objectax.hist(nums1, label="nums1", histtype="step", density=True) # Plot histogram of nums1ax.hist(nums2, label="nums2", histtype="step", density=True) # Plot histogram of nums2plt.legend()plt.show()
